SHEARS FOR DEHORNI NG ANIMALS.

SPECIFICATION forming part of Letters Patent No. 441,065, dated November18, 1890.

Application filed July 30, 1887. Serial No. 245,724. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES D. GREEN, a citizen of the United States,residing at Arcadia, in the county of Crawford and State of Kansas, haveinvented certain new and useful Improvements in Dehorning-Shears and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

Figure l of the drawings is a representation of this invention, and is aperspective View, the wooden handles of the shears beingbroken oif. Fig.2 is a bottom view, partially open, only the metal portion of thehandles being shown. Fig. 3 is a top view closed. Fig. 4 is a verticalsection, the handles being broken off atthe ends.

The invention is a device for dehorning young cattle or calves, theobject being to amputate the horn as quickly, as readily, and with aslittle pain as possible; and it consists in the construction of theblades and their combination with the handles in such manner that theblades can be passed downward from above on a horn to be cut, with theircutting-edges downward, as hereinafter described, and embraced in theappended claims.

Referring to the drawings by letter, A A designate the respective bladesof the dehorning device or shears, similar in shape, but the blade Aslightly smaller than the blade A, so that the former may have its endsinserted between those of the latter, and be pivoted thereto at a neartheir corners on both sides. The said blades are formed at their centralcurved portions B B on semicircles, and have their edges Z) I) beveledfrom without inwardly, as shown in Fig. 4. The blades, between theircentral curved portions and their ends, extend straight and parallel oneach side toward each other, as at O, the ends of the blade Aoverlapping those of the blade A at their pivoted points, so that whenthe blades are turned together the edges cut from a considerable angleon each other before they bind on the horn over which they are passed.

D D are the respective handles to the blades A and A, which handles aremade of wood and in practice are about two feetlong. The handles arefirmly secured by rivets,

screws, or otherwise to the projections cl d integral with and standingfrom the central parts of the corresponding edges of their respcctiveblades. The handles are at such angles to the blades that When thecutting-edges are together throughout their entire extent the handlesare quite or nearly in line with each other, and their ends in oppositedirections.

The method of using the tool or shears is as follows: The blades A A arepassed downward over the horn to be amputated, the cutting-edges beingdownward and the handles standing front and rear. The latter are thenturned, the cutting-edges binding on the horn when the opening betweenthe same has shortened,till it is about circular. Then by continuing toclose the handles the blades are caused to bite into the horn, thecentral parts shearing through in the direction between the handles,while the side portions of the edge of the blade A shear past those ofthe blade A, and make a downward and inward cut, causing the end of thestump to be concave. The horn is thus cut off at the level of the endsof the hair, or near that position.

The amputation can be done very quickly and readily, avoiding all painand danger, and is a great improvement over the use of the saw, theknife, or the heated iron.

Having described my invention, I claim- 1. An implement to dehorncattle, consisting of two curved shearing-blades pivoted together toembrace the horn, and suitable handles whereby such blades are actuated,substantially asspecified.

2. The herein-described dehorning-shears, composed of the two bladesmade at their central portions on arcs of circles, and having suitablecuttingedges, one being slightly smaller than the other to permit themto be pivoted together near the corners of their straight parallel endportions, and the handles secured to the respective blades in suchmanner that they will be quite or nearly aligned when the edges of theblades meet throughout their entire length, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES D. GREEN.
